Sp ecification of Application and June as,

To all whom it may concern:

Be it known thatwe, FosT-En BA'ssE'rcr and VVILIJAM A. HUNTER, Jr, ctt1zens of;

the United States, residing at Los- Angeles,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

This invention contemplates the oonstruction of a flushing valve provided with means I for controlling the flow of the flushing water arranged to be located at a point distant I from the supply tank and near to the eduction point.

One of the objects of the invention is the production of a flushing valve capable of being operated from a oint distant from the supply tank, comprising a chambered casing having a main valve and an auxiliary valve, the main valve'being partially controlled by water pressure.

Another object of the invention is the'production of a flushing valve comprising means for' controlling the admission of air into the flushing pi'pe in such a manner that the action of the valves will be rendered positi ve.

Withthese and other objects in View, the invention consists of certain novel features of construotmn, combination and arrangement of parts as will be described and particularly pointed out in the appended-claim, I and in the drawings, in which, Figure 1 1s a vertical sectional view of ourimproved valve mechanism, showing the main valve and the auxiliary valve posi-- 'tioned on their seats; Fig. 2 is a vertical sectional .view show-in the main valve and the auxiliary valve raised from their seats; Fig. 3 is a. horizontal sectional view taken .on the. line 3-3 of Fig. 1; Fig. 4 is a I similar view taken on the line 44"of Fig.

1; a-nd. Fig. 5 is a vertical'sectional view of a modification.

Qorrespo'nding and like parts" are referred to in the -following.descrlption and in all of the views of the drawings by thesame reference characters. Y

In the drawings 1 denotes a main casingh'avmg connections 'at' 2'to adistantsu ly' tank. The main casing 1 is formed w t a Letter in nt Patented May 3, 1910.

1909. Serial No. mm.

ing pipe, is connectedto .said bottom sections so as to surround the valve seat. A second casing, 5, is supported in the casing,

1, on legs, 6, which rest upon the sec tion of the main casinv L The casing, 5,-

. is formed with a plurality of lateral ports, 1', which are V-shaped, with their narrow portions facing upwardly and the upper portion of' the valve casing, 5, is. provided with :a washer, 8, which is .itioned against the inner sides of the'casin and at a short distance from the inner si e of the top.-

1 A valve, 9, formed with a semi-spherical bottom portion is adapted to move upwardly in the casing, 5, and is normally seated on the valve seat, 3. Normall the valve, -9, closes the major portion of e ports, 7, and

said valve is formed with an opening, 10,

'- this purpose is guided by a spider, 12, which is positioned against the inner side of the flushing pipe, 4. The member 11 is provided'with a plurality of spiders, 13, which are spaced apart and interiorly positioned on said member.

A valve 1 1 having a stem 15 is adapted to be seated on the upper portions of the valve 9, and the stem 15 is arranged to extend downwardly through the valve 9 and they spiders 13 therein. An operating rod 16 having azshouljder 17" formedthereon, ex-, tends upwardly through the tubular mem ber 11 and is' adapted to engage the lower end of the valve stem 15 and is guided by the spiders 13.

The-rod 16 and-the tubular;

member 11 are engaged by an operating l lever 18 which'extends through an-opening formed in the flushing-pipe .4, and 1s pivoted thereto asat '19. The innerend is bent as at 20in order to properly engage the lower end of the tube ll'and the op- 1 crating rod 16. This lever 18 1s operated by a suitable rod 211 An annular snifting:

valve '22is mounted on the flushing pipe 4.;

a-t a'point immediately below the valve seat.

3 and the opening of said .valve preferably faces-downwardly? Normally the flushing water fills the interiorof casing, 5, and-casing, v1, so thatthe pressure in both casings ,.w1ll be, substanvalve seat, 3, on a bottom section, and-a flushtially equal, When it-is desired to ,open'the .seat onthe top of valve, 9, an water contained within the casing 5 to flow.

valves the lever, 18, is depressed on its outer end, thereby raising the, valve 14:, from its (1 allowing the through the tubular member, 11, downwardly into the flushing pipe, 4. As the 0 ratin lever, 18, is still further depressd, t e tub ar member 11 carrying the valve 9 will be moved upwardly in the casing 5,

temporarily closing the ports, 7, and opening communication between the casing 1 and the flushing pipe, 4, and as the valve, 9,

is thus moved off its seat, the flow of waterthrough the bottom opening in thecasing I will tendto lift the valve away from its seatand bring the top thereof in contact with the washer, 8,and thereb open the ports, 7. This lifting of the va vs 9 will operate to thoroughly cleanse the ports 7 from any sediment .that may'have accumulated therein. When the water from the supply tank has passed through the flushin pipe, the valve 9-wi1l graduallyffall to its seat and the valve, 14, will fall to its seat, while the 'snifting-valve,'22, willopen upwardly so as to allow air .-to,'fill'the flushing pipe, 4,

thereby preventing any lifting or arr ng of the'valve 9 from 'or'on its seat. This ar- 'rangement assures a :water-tight connection between the valve 9, anditsseatand prevents any water rom flowing'through the flushing pipe 4 when the same is normally seated. When .the valve 9 normally rests onits seat, the pressure of the waterwill tend to hold the same thereagainst; "The open- 'ing in-the flushing pipe, 4:, through which the operating lever,'-18 extends "may be closed by anysuitabla evice adapted for this purpose.

In 5 we have-illustrateda modificatiCIL'Of'OIII valve mechanism comprisi'ng'a' suitable tank, 23, which is mounted on the flushing pipe and extends above the valve mechanism which it incloses. The tank, 23,

is provided'with connections, 24., communieating with the main water supply.

A Having thus describ'edour invention, what we claim as new and desire to secure by Letters-Patent, is:

A flushing valve mechanism comprising a main flushing pipe, an outer valve casing communicating with said pipe, an inner casing supported in the outer'casing and commilnicating therewith, said inner casing having triangular openings therein, a valve formed with a semispherical seat portion movablein,the inner casing and adapted when seated to close the broad end of said triangular openings,.a second valve movable in the first mentioned valve, a conduit extending through the first. mentioned valve witnesses.
